By transmitting the signal received at a specific signal to each of a plurality of cabinets, the display apparatus 100 according to an embodiment may provide an image through an entire screen even if a signal transmission error occurs in any one of cabinets.

For example, referring to FIG. 5, even if a signal transmission error occurs between the fourth and fifth cabinets 504, and 505, and the fifth cabinet 505 fails to receive a signal from the fourth cabinet 504, the fifth cabinet 505 may provide an image using the signals received from the second, sixth, and eighth cabinets 502, 506, and 508.

FIG. 6 is a view illustrating a method for signal processing of a display apparatus according to an embodiment.

As described above, the cabinet 110 may transmit a signal to another adjacent cabinet via a plurality of wireless communicators provided in the cabinet 110. The specific cabinet of the display apparatus may receive a plurality of signals from another adjacent cabinet via a plurality of wireless communicators.

For example, referring to FIG. 6, when first, second, third, fourth, fifth, sixth, seventh, eighth and ninth cabinets 601, 602, 603, 604, 605, 606, 607, 608, and 609 are combined in the arrangement of 3×3, the fifth cabinet 605 may receive a signal from each of the second, fourth, sixth and eighth cabinets 602, 604, 606, and 608.

The processor 150 may provide an image based on the signal received via a wireless communicator disposed in a first direction according to a predetermined priority.

The predetermined priority may be determined variously depending on a user command. For example, referring to FIG. 6, the priority of each wireless communicator that transmits a signal to each of the first, second, third, . . . , and eighth, and ninth cabinets may be set to be higher than the priority of another wireless communicator.

The processor 150 may provide an image based on the signal received from the fourth cabinet 604 among the signals transmitted from the second, fourth, sixth, and eighth cabinets 602, 604, 606, and 608 to the fifth cabinet 605.

Although a single cabinet receives a plurality of signals, a single signal may be processed by a predetermined priority, and thus a modular display apparatus according to an embodiment may reduce the load of the processor.

The processor 150, when it is identified that no signal is received via the wireless communicator in the first direction, may provide an image based on the signal received via the wireless communicator provided in a second direction according to the predetermined priority.

The processor 150, when it is identified that no signal is received via a wireless communicator having higher priority, may provide the image through the signal received via a wireless communicator in a following priority.

Accordingly, the modular display apparatus 100 according to an embodiment may provide an image through an entire screen even if a signal transmission error occurs in any one of the cabinets.

The processor 150, when it is identified that no signal is received via the wireless communicator disposed in the first direction, may generate information on the transmission error of the wireless communicator disposed in the first direction, and provide the generated information through at least one cabinet.

For example, when it is identified that no signal transmission is performed between the fourth and fifth cabinets 404, and 405, the processor 150 may display a message that the signal transmission error occurs between the fourth cabinet and the fifth cabinet on one area of the display apparatus 100 as shown in FIG. 7.

As shown in FIG. 7, even if the signal transmission error occurs in the fifth cabinet 605, the fifth cabinet 605 may provide an image based on the signal received from each of the second, sixth and eighth cabinets 602, 606, and 608 other than the fourth cabinet 604. Therefore, the display apparatus 100 may provide an image through an entire screen.
